A cabbage picked at Draynor Manor is unlike other cabbages; when eaten, it heals 200 life points and gives a +1 to +2 Defence boost for a short amount of time. During the now-replaced Black Knights' Fortressquest, players learned that Draynor Manor cabbages are enchanted (as is everything that grows at the manor), and that is why it tastes better than other cabbages.

The cabbage's Defence boost does not stack with other Defence boosts, regardless of the order in which boosts are activated.

During the 2009 April Fools event, cabbages in the Falador cabbage patch would bounce and hop around when picked and could be wielded. However, players could not wield a Draynor Manor cabbage; the chatbox would say, 'This type of cabbage seems disinclined to being wielded.'

If you tried to use one of these cabbages during the sabotage part of the Black Knights' Fortress quest you would receive a warning message saying "This is the wrong sort of cabbage!" and afterwards your character would say "I'm not supposed to be HELPING the witch you know..."

This cabbage cannot be stored in a sack, as it is different from the standard cabbage that can be stored. This also means it cannot be used as payment for farmers to watch over tomatoes or Krandorian hops.

Draynor Manor cabbages used to be tradeable, and, because of their Defence boost, sold for a fair price on the Grand Exchange. An update, however, has made them untradeable on the Grand Exchange.
